    • Method of manufacturing a metal cord with three concentric layers (C1, C2, C3), rubberized in situ, of M+N+P construction, comprising a first, internal, layer (C1) consisting of M wires of diameter d1, M varying from 1 to 4, around which there are wound together in a helix, at a pitch p2, in a second, intermediate, layer (C2), N wires of diameter d2, N varying from 3 to 12, around which there are wound together as a helix at a pitch p3, in a third, outer, layer (C3), P wires of diameter d3, P varying from 8 to 20, the said method comprising the following steps which are performed in line: an assembling step by twisting the N wires around the first layer (C1) in order to form, at a point named the “assembling point”, an intermediate cord named a “core strand” of M+N construction; downstream of the assembling point, a sheathing step in which the M+N core strand is sheathed with a rubber composition named “filling rubber” in the uncrosslinked state; an assembling step in which the P wires of the first layer (C3) are twisted around the core strand thus sheathed; a final twist-balancing step. Also disclosed is a device for implementing such a method.
    • 制造具有M + N + P结构原位橡胶化的三个同心层(C1,C2,C3)的金属帘线的方法,包括由直径为d1,M的M线组成的第一内部层(C1),M 1至4,其中以螺旋线,间距p2,第二,中间层(C2)缠绕在一起,直径为d2的N个线,N为3至12个,绕其缠绕在一起 作为在间距p3,第三,外层(C3)中的螺旋线,直径为d3的P线,P从8变化到20,所述方法包括以下步骤:串联进行组装步骤 在第一层(C1)周围的N条线,以便在称为“组装点”的点处形成称为M + N结构的“芯线”的中间线; 在组装点的下游,在未交联状态下用M + N芯股线用称为“填充橡胶”的橡胶组合物包覆的护套步骤; 组装步骤,其中第一层(C3)的P线绕着包芯的芯线绞合; 最后的扭曲平衡步骤。 还公开了一种用于实现这种方法的装置。
